AG1 is marketed as an easy way to boost your intake of important vitamins, minerals, and plant compounds. While it may be helpful for some, it isn’t safe or worth the cost for everyone.
AG1 (previously known as Athletic Greens) is a popular greens supplement, largely made famous by social media. From Instagram influencers to podcast and social media ads, it seems as though everyone is singing its praises to the sun and back.
But at almost $100 per package, is this AG1 really worth buying?
We dove into the nutrition and science behind AG1 and tested the product ourselves to help you decide.
AG1 was founded in 2010 by New Zealand native Chris Ashenden, the current CEO, as a way to make optimal performance and nutrition easy and convenient.
AG1 is a supplement company with one product, also called AG1. The supplement is a greens powder created to help fill nutritional gaps in your diet. The powder includes 75 vitamins, minerals, probiotics, whole food-sourced plant compounds, and adaptogens meant to promote optimal health for its users.
The company claims that daily use of this greens powder supports energy levels, immune health, gut health, healthy aging, and hormonal and neural health.

AG1 includes four proprietary blends, all of which contain a variety of herbs, powdered fruits and vegetables, plant extracts, and other nutrients that may have some health benefits.
Just keep in mind that the company does not disclose the exact amount of each ingredient in these blends, so it’s impossible to know whether a given ingredient is present in a large enough dose to have a meaningful effect.
Alkaline, Nutrient-Dense Raw Superfood Complex
This blend is made of several nutrient-dense ingredients, including spirulina. According to the company, the ingredients were chosen based on their ability to support a healthy gut microbiome and various other aspects of health.
For example, several ingredients — including bilberry fruit extract,
Ingredients: organic spirulina, lecithin, organic apple powder, inulin, organic wheat grass juice powder, organic alfalfa powder, organic chlorella powder, organic barley leaf, acerola fruit juice powder extract, broccoli flower powder, papaya fruit powder, pineapple fruit concentrate, bilberry fruit extract, beetroot powder, rosehip fruit powder, carrot root powder, spinach leaf powder, cocoa bean polyphenol extract, grape seed extract, green tea extract, licorice root powder, lycium berry fruit extract, ginger rhizome powder, slippery elm bark powder, kelp whole plant powder
Nutrient Dense Extracts, Herbs, and Antioxidant
This blend features antioxidants, plant extracts, and herbs, including adaptogens.
Adaptogens are herbs that may help your body better adapt to stress, according to
Ingredients: alkaline pea protein isolate, citrus bioflavonoids extract, artichoke leaf extract, citric acid, rhodiola root, eleuthero root extract, rosemary leaf extract, milk thistle seed extract, R,S alpha-lipoic acid, ashwagandha root extract, dandelion whole plant dry concentrate, hawthorn berry extract, beta-glucans, policosanol, coenzyme Q10, stevia leaf powder, vitamin K2
Digestive Enzyme and Super Mushroom Complex
According to the company, this blend features ingredients with naturally occurring enzymes to support digestion and nutrient absorption.
Ingredients: astragalus root powder, bromelain, burdock root powder, reishi mushroom powder, shiitake mushroom powder
Dairy-free probiotics 7.2 billion CFU
The final blend includes two strains of probiotics:
- Lactobacillus acidophilus: This is a common, beneficial probiotic that is found in your body and added to foods and supplements.
Research from 2022has found that this strain can help regulate the balance of your gut microbiome by reducing intestinal pH, which helps keep “bad” bacteria, such as Escherichia coli (E. coli), from colonizing in your gut.
- Bifidobacterium bifidum:
Research from 2021shows that this beneficial probiotic, which is found in the gut of infants and adults, may help fight inflammation, infection, and discomfort from lactose intolerance and constipation.
Healthline editor Christy Snyder tested AG1 daily for about a month, and this is her feedback.
How I used it
“I found that drinking 1 scoop of the AG1 as directed with 8–10 ounces (oz) of water wasn’t quite right for me. I ended up measuring out 12 oz of water to go with the AG1. It’s a flavor personal preference; it was a little too intense for me at both 8 oz and 10 oz of water. 12 oz is the sweet spot for my palate.
“I find that the AG1 bottle itself works best for mixing the powder into water. It is absolutely better shaken and not stirred.
“I like having it in the morning after I do my a.m. bike ride. I was pretty consistent but not perfect. It’s important to read the directions because the brand recommends that you take AG1 first thing in the morning on an empty stomach for optimal absorption.
“At first, I was drinking AG1 along with my eggs and fruit for breakfast, then realized I might want to test it on an empty stomach. Honestly, I don’t think it truly matters whether you take it on an empty stomach or not (the brand’s marketing materials says AG1 works at any time of day).”
Taste and texture
“I liked the taste of AG1 far more than I expected to. It is similar to a matcha taste. That’s really the closest thing I can compare it to. It’s not bitter; it’s lightly sweet. It does taste “green” if that makes sense, but not in a bad way. It doesn’t taste like kale. It’s actually very pleasant, and I looked forward to drinking it every day.
“If you shake it well (and shake the bottle a few times throughout your drinking experience) it tends to be less grainy and better mixed together, as you’d expect. The bottle it comes with works well for mixing in the powder.”
“I noticed that my nails started growing faster. Other than that, I couldn’t detect any other changes caused by it. It’d be nice to get bloodwork to see if there were any trackable wins from taking AG1 for a month.
“I do think AG1 would be great for folks looking to cut out having to take multiple vitamins and supplements. Like, I take a multivitamin and pre/probiotic pills separately, so it was nice to skip them for a bit and just try this.
“I also know that I don’t get my daily servings of fruits and vegetables; I tend to come in very low despite making my best effort. So I did feel like I was being healthier. But without any health data, I’m not sure if it’s worth the price.”
“It’s a tasty drink in my opinion, but I am not necessarily convinced it is worth the price and subscription. It seems like a good option for anyone who would like to reduce their supplement intake from multiple products into one simple drink. It’s great to know that you can get it all from one thing.”
Here’s a breakdown of how much AG1 costs, as well as key details about shipping and returns:
|Single monthly subscription|
|Double monthly subscription|
|The Pouch||$99 ($3.30 per serving)||$79 ($2.63 per serving)||$149 ($2.48 per serving)|
|Travel Packs||$109 ($3.63 per serving)||$89 ($2.97 per serving)||$169 ($2.82 per serving)|
Shipping costs $9 for deliveries to the United States, Canada, and Australia. European shipping rates vary. The company also ships to China through the AG1 WeChat store.
If you’re unhappy with your purchase for any reason, you can return your AG1 for a full refund within 90 days of delivery.
While AG1 has not been studied to confirm its safety or effectiveness, it does have some potential benefits.
Provides several essential nutrients and antioxidants
One serving of AG1 provides more than 100% of the DV for several vitamins, including vitamins C and E and all 8 B vitamins. It’s also a good or excellent source of several other essential vitamins and minerals.
This means that, like a multivitamin, AG1 is a potentially convenient way for people to bridge nutrient gaps in their diet.
The supplement also contains several herbs, vegetable powders, fruit powders, and plant extracts that are rich in important plant compounds such as antioxidants and polyphenols.
May help boost energy levels
Many customers say they notice increased energy levels after taking their daily AG1 supplement.
AG1 contains high doses of all eight B vitamins.
Drinking AG1 may therefore provide an energy boost for customers who are not currently meeting their vitamin B needs through diet alone.
Use caution if you’re eating foods high in B vitamins or taking other supplements with B vitamins. There is some evidence of negative side effects of excessive doses of vitamins B6 and B12 that could lead to temporary neuropathy and acne.
The company’s website also mentions wheatgrass as a potential energy-boosting ingredient.
May support gut health
AG1 includes sources of prebiotics and probiotics, which may benefit gut health.
Still, keep in mind that pre- and probiotics are not recommended for everyone.
While probiotics may be indicated for certain individuals, such as those with traveler’s diarrhea or irritable bowel syndrome, some
Additionally, prebiotics such as inulin may cause
Third-party tested and safe for sport
AG1 products are NSF Certified for Sport. This certification ensures that AG1 is free of substances banned by most competitive sports organizations.
This certification also indicates that the product has been tested for purity and potency. This means you can trust that AG1 contains the ingredients listed on the label and that it doesn’t contain unsafe levels of heavy metals or other contaminants.
Suitable for a variety of diets
AG1 is suitable for several dietary patterns, including:
- low carb
The supplement is also free of gluten, dairy, corn, egg, peanuts, lactose, sucrose, dextrose, and artificial colors, preservatives, and sweeteners.
Along with the numerous potential benefits of taking this greens powder, there are some significant downsides to consider.
Not a substitute for whole fruits and vegetables
The company markets AG1 as having the same antioxidant content as 12 servings of fruits and vegetables. This may lead some consumers to believe that the powder is a replacement for whole fruits and vegetables.
While AG1 does provide some important nutrients that are found in fruits and vegetables, there’s currently not enough evidence to show that consuming powdered forms of produce offers the same health benefits as eating the whole foods.
Additionally, AG1 doesn’t offer the same boost of fiber that you would get from eating whole fruits and vegetables.
Therefore, while it can help you get closer to meeting your fiber needs, you’ll still need to make sure you’re eating plenty of fiber-rich foods throughout the day, such as whole grains and whole fruits and vegetables.
Lacks vitamin D and iron
This all-in-one nutritional supplement doesn’t include iron or vitamin D, two nutrients that a large percentage of the population needs more of.
In fact, one survey suggests that
If you’re low in either of these nutrients, you’ll need to take an additional supplement to meet your needs.
Does not list proprietary blend ingredient amounts
Because AG1 does not list the exact amount of each ingredient in its proprietary blends, it’s impossible to know whether you’re getting an effective dose of any of those ingredients.
Unknown ingredient amounts can also be problematic for people who are sensitive to any of the ingredients in the blends.
May cause stomach upset
Some users report experiencing upset stomach, bloating, and diarrhea after taking AG1, which could be related to the inclusion of probiotics or inulin.
Starting with a smaller amount of the powder and working your way up to a full serving may help minimize these effects.
Not appropriate for people taking certain medications
AG1 contains several ingredients that can interact with prescription medications such as:
- hormonal birth control
- some diabetes medications
- high blood pressure medications
- thyroid hormones
- blood thinners
Before taking AG1, make sure to talk with a healthcare professional to find out whether it’s safe for you.
Not safe for everyone
In addition to people who are taking certain prescription medications, AG1 may not be safe or appropriate for the following populations:
- People who are pregnant or breastfeeding: Many of AG1’s ingredients have either been shown to be unsafe or have little or no research on their safety in people who are pregnant or breastfeeding.
- Children: Only adults should consume AG1. The supplement contains ingredients that have not been proven safe for children and provides vitamin and mineral doses that are excessive for kids.
- People with certain autoimmune conditions: AG1 contains alfalfa, which is generally not recommended for people with some
autoimmune conditions, such as lupus.
- People with end stage kidney disease: Because the supplement contains potassium and phosphorus, it may not be appropriate for people with end stage kidney disease.
If you have any concerns about whether AG1 is safe for you to take, be sure to talk with a trusted healthcare professional.
AG1 is manufactured in a facility that complies with the
During Healthline’s internal vetting process, we noted that AG1 doesn’t make any disease claims or unacceptable health claims about its product. However, the research and clinical evidence supporting several of its ingredients is limited.
The company has also invested heavily in an influencer marketing strategy. Many influencers who advertise AG1 products make health claims about the product even though they are not qualified nutrition or healthcare professionals.
The company has been involved in two lawsuits. In 2015, the state of California alleged that AG1 products may be exposing consumers to levels of lead that exceed the threshold established under the Safe Drinking Water and Toxic Enforcement Act of 1986.
More recently, in 2020, a former employee filed an alleged employment discrimination complaint. The lawsuit was dropped in 2022.
At time of publish, AG1 has a Better Business Bureau (BBB) rating of B- but is not BBB accredited.
On Trustpilot, AG1 has a rating of 3.9 out of 4 stars, based on more than 30 customer reviews.
Happy customers say they have noticed improvements in various aspects of their health, such as increased energy levels, clearer skin, and improved digestion. Several also say the powder tastes better than they expected.
Negative reviews mention a lack of noticeable benefits given the high cost. Some people say they dislike the flavor, and others complain that they had issues with billing and difficulties canceling their subscriptions.
AG1 isn’t the only greens supplement on the market.
Most products failed because they make unsubstantiated health claims, especially around detoxing. Others didn’t make the cut because they are noncompliant with
Here’s a closer look at how AG1 compares with the other greens powder product that passed our vetting process and dietitian review:
Whether AG1 is worth the cost greatly depends on your diet, nutritional needs, and budget.
Because the supplement includes multiple vitamins, minerals, probiotics, and plant compounds, it may be worth trying if you:
- have increased nutrient needs that you cannot meet through diet alone
- follow a restrictive dietary pattern and are looking for a multi-nutrient supplement
- have difficulty eating a balanced diet
- are a competitive athlete looking for help meeting your nutritional needs
Still, keep in mind that while AG1 contains some research-backed ingredients, there’s currently no research to support its effectiveness.
Therefore, it may not be worth the cost for people who already take a multivitamin or maintain an overall balanced diet.
Furthermore, AG1 may not be safe or appropriate for certain populations, including:
- people who are pregnant or breastfeeding
- people who are taking certain prescription medications
- people with end stage kidney disease
- people with certain autoimmune conditions
Before trying any dietary supplement, talk with a trusted healthcare professional to ensure that the product is safe and appropriate for you to take.
What are the side effects of AG1 (previously Athletic Greens)?
Some people report stomach upset, bloating, and diarrhea after starting AG1. To help minimize the risk of unwanted side effects, it's recommended to start with a smaller dose of AG1 and slowly increase the amount over a few days until you reach a full scoop.
Is AG1 as good as eating vegetables?
There's currently no research to show that consuming vegetables in powdered form has the same health benefits as eating whole fruits and vegetables.
Therefore, although AG1 contains several important nutrients found in produce, it should not be used as a replacement for eating whole food sources of those nutrients, such as leafy greens and other vegetables.
Do you lose weight on Athletic Greens?
AG1 can be an easy way to get several essential nutrients with one low-calorie drink, but it won't affect weight or weight loss on its own.
What does Athletic Greens do to your body?
AG1 provides the body with 75 vitamins, minerals, and whole food ingredients, many of which support digestion, energy levels, and mood.
In addition to many essential vitamins and mineral that your body needs for optimal function, it also includes probiotics to support a diverse and healthy gut microbiome.
AG1 offers a convenient but expensive way to help fill nutrient gaps in your diet. Many of the product's ingredients have some research to support their benefits, and happy customers note that they've noticed a boost in energy levels since trying the supplement.
However, no studies have been performed to confirm the safety or effectiveness of AG1. And because most of its ingredients are present in proprietary blends, it's impossible to know whether AG1 contains effective doses of these ingredients.
While it should not be a replacement for eating whole fruits and vegetables, AG1 may be worth trying if you're looking for an easy way to boost your intake of important vitamins, minerals, and plant compounds. Just make sure to talk with a healthcare professional first!
